� August 10, 2011 <br /> 190 Ft Self-Supporting Tower Structural Analysis A2G0082A Pasco County (VS) <br /> Project Number 110908, Revision 3 Page 3 <br /> 1) INTRODUCTION <br /> This tower is a 190-ft self-supporting tower designed by Valmont in November of 1998 The tower was originally <br /> designed for a fastest mile wind speed of 105 mph with no ice and 50 mph under service loads per TIA/EIA-222- <br /> F for the appurtenances listed in Table 2. TEP did not visit the site. All information provided to TEP was <br /> assumed accurate and complete. <br /> 2) ANALYSIS CRITERIA <br /> The structural analysis was performed for this tower in accordance with the requirements of ANSI/TIA-222-G-2- <br /> 2009 Structural Standard for Antenna Suoportinq Structures and Antennas — Addendum 2 using a 3-second <br /> gust wind speed of 110 mph with no ice and 60 mph under service loads with the following criteria: <br /> 1) Type of Analysis: Rigorous Structural Analysis <br /> 2) Classification of Structure: Class II <br /> Definition: Structures used for services that due to height, use or location represent a significant <br /> hazard to human life and/or damage to property in the event of failure and/or used for senrices that <br /> may be provided by other means. <br /> 3) Exposure Cateaorv� Exposure B <br /> Definition: Urban and suburban areas, wooded areas, or other terrain with numerous closely <br /> spaced obstructions having the size of single-family dwellings or larger. <br /> 4) Topographic Cateaory Category 1 <br /> Definition. No abrupt changes in general topography, e.g. flat or rolling terrain, no wind speed-up <br /> consideration shall be required. <br /> 5) Earthquake Cateaory: Not Considered <br /> Commentary: Earthquake effects may be ignored per this Standard for site locations where Ss <br /> does not exceed 1.0.
